UNIVERSAL JOINT.

Specification of Letters Patent.

Patented Sept. 15, 1908.

Application filed. December 10, 1907. Serial No. 405,896.

, To all whom it may concern:

Be it known that I, TRACY V. BUOKWAL- 'rnn, a citizen of the United States, residing at Altoona, in the county of Blair and State of Pennsylvania, have invented certain Imrovements in Universal Joints, of which the following is a specification.

This invention is a universal joint designed particularly for transmitting rotary motion with the minimum friction and wear, and to this end it comprises a novel arrangement of ball bearings. providing motion in transverse planes.

In the accompanying drawings, Figure 1 is an irregular sectional view representing an application of invention; Fig. 2 is a sectional view of the same mechanism transverse to the view shown in Fig. 1; Fig. 3 is an irregularsectional view of the same mechanism transverse to the views shown in Figs. 1 and 2; and Fig. 4 is an irregular sectional view representing a further application of the invention.

As represented in the drawin s, the invention comprises a bearing mem er I having an exterior circular race 1, a bearing member 2 having the interior circular race'Z concentric with the race 1 and the diametrically dis osed bosses 2", balls 3 disposed between t e bearing members in the races, bearing members 4 fixed on the bosses 2 and having the exterior circular races l disosed at right angles to the races 1 and 2,

' caring members 5 having the interior circular races 5 concentric with the races 4, and balls 6 disposed between the bearing members 4 and 5. The bearing member 1 is fixed to a shaft 7 having the bifurcations 7 forming a yoke in which the bearing member is held by the bolt 8, the bifurcations having the flanges 7 overlapping the bearing member 2.

As shown in Figs. 1, 2, and '3, a toothed ring or wheel 9 has the rectangular interior recesses 9 in which the bearing members 5, of rectangular exterior contour, are fixed, and fixed to the faces of the ring by the bolts 10 are the circular plates 9 which overlap the bearing members 5.

-As shown in Fig. 4, the bearing members 5 I are fixed to a shaft 11 having a yoke formed by thebifurcations 11 in which the bearing members are fixed. It will be observed that in transmitting power in either direction through the parts thus connected, the angle of the axes of revolution of the driving and claims, signifies a bearing member having an annular surface.

Having described my invention, I claim:

1. A universal joint comprising a pair of bearing members having concentric races, balls in said races, asecond pair of bearing members having concentric races, and balls in said races last named, the exterior bearing member of said first pair being fixed to the interior bearing member of said second pair so that the two sets of balls act transverse lanes. p 2. A concentric annular bearing members, balls between said bearing members, the exterior of said bearing members having diametrically disposed bosses thereon, an annular bearing member fixed on each of said bosses,

an annular bearing member concentric with each of said last named bearing members, and balls disposed between said last named concentric bearing members.

3. A universal joint comprising an annular.

bearing member, a concentric annularbean mg member exterior thereto, balls between said bearing members, one of said bearmg ,members having a flange fixed thereto and overlapping the other of said bearing members, a pair of diametrically disposed annularbearing members fixed to said exterior bearing member, an exterior annular bearing member concentric with each of said diametrically disposed bearing members, 1 and balls between the last named concentric bearing members.

,4. A yoke, an annular bearing member between the bifurcations of said yoke, means for fixing said parts together, anannular bearing member exterior to the first named bearing member, balls between saidbearing members, parallel annular bearing members fixed diametrically to said exterior bearing member in planes transverse thereto, an annular bearing member exterior to each of said parallel bearing members, balls between the corresponding members of the last named imiversal joint comprising a-pair of eee eee bearing members, and s power transmitting ing said third mentioned race-ways, balls member fixed to said. last named exterior bearing members.

5. The combination of s, journeied shaft, a bearin member With a race We-y carried by said shart, a second bearing member with a race-way surrounding said first reee way, bells disposed between said race-Ways, bearing members carried by said second bearing member with race-Ways disposed transversely to the plane of said first named race-Ways, bearing members having race-Ways surround disposed between said third and fourth mentioned race-Ways, and power transmission mechanism fixed to said last named bearing members.

In Witness whereof I have hereunto set my name this 7th day of Dee, 1907, in the presence of the subscribing witnesses. .7
